A grade that is too soft will flow under heavy traffic and high heat; a grade that is too hard will crack in the cold. The right decision arbitrates between these two risks, taking into account availability and the delivered price.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In practice, we start from your laying area and your<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Finally, bear in mind that the grade is only part of the quality equation. Two batches of the same bitumen grade may differ in their origin, their storage stability or their ageing behaviour. That is why we attach as much importance to traceability and the certificate of analysis as to the classification itself: a good grade choice that is poorly sourced remains a bad purchase.<\/p>","protected":false},"excerpt":{"rendered":"<p>N\u00e9goce de bitume Bien choisir son grade de bitume selon le climat et le trafic Une fois les familles de grades de bitume comprises, reste la question pratique : lequel commander pour votre chantier ?
